IMPROVEMENT IN CARPET-STRETCHERS.

Specification forming part of Letters Patent No. 138,450, dated April 29, 1873i application file April 2, 1873.

To all whom it may concern: V

Be it known that I, CHARLES TERRY, oi the city and county of St. Louis and State of Missouri, have invented a certain Improvement in Carpet- Stretchers, of which the following is a specification:

My improvement consists in the construction of the clamp; in this a rib projects upward from the free end of the lever, and a presser-block is connected bya strap to the under side of the lever, the length of the strap being such as to extend around in front of the lever, and to allow the block to fall to the rear of the rib, as shown, to hold the carpet edge tightly without piercing it or drawing the threads.

Figure 1 is a perspective view of' the machine. Fig. 2 is a longitudinal sectional elevation of the machine with the carpet clamped thereln and the claws in position on the floor.

The machine consists of a lever, A, having at the rear end fulcrum-claws a, which hold against the floor. B is a rib, arising from near the front end of A, and forming the fixed part of the clamp. O is a presser-block, forming the movable part of the clamp, and connected by a strap, D, to the bottom of the lever A. E (see Fig. 2) shows the edge of the carpet as held inthe stretcher. F is the floor.

The operation of the machine is clearly
